# OmniVoice 🌍
OmniVoice is a massively multilingual zero-shot text-to-speech (TTS) model supporting over 600 languages. Built on a novel diffusion language model-style architecture, it delivers high-quality speech with superior inference speed, supporting voice cloning and voice design.
- **Paper:** [OmniVoice: Towards Omnilingual Zero-Shot Text-to-Speech with Diffusion Language Models](https://huggingface.co/papers/2604.00688)
- **Repository:** [GitHub](https://github.com/k2-fsa/OmniVoice)
- **Demo:** [Hugging Face Space](https://huggingface.co/spaces/k2-fsa/OmniVoice)
## Key Features
- **600+ Languages Supported**: The broadest language coverage among zero-shot TTS models.
- **Voice Cloning**: State-of-the-art voice cloning quality from a short reference audio.
- **Voice Design**: Control voices via assigned speaker attributes (gender, age, pitch, dialect/accent, whisper, etc.).
- **Fine-grained Control**: Non-verbal symbols (e.g., `[laughter]`) and pronunciation correction via pinyin or phonemes.
- **Fast Inference**: RTF as low as 0.025 (40x faster than real-time).
- **Diffusion Language Model-style Architecture**: A clean, streamlined, and scalable design that delivers both quality and speed.
## Sample Usage
To get started, install the `omnivoice` library:
> We recommend using a fresh virtual environment (e.g., `conda`, `venv`, etc.) to avoid conflicts.
**Step 1**: Install PyTorch
NVIDIA GPU
```bash
# Install pytorch with your CUDA version, e.g.
pip install torch==2.8.0+cu128 torchaudio==2.8.0+cu128 --extra-index-url https://download.pytorch.org/whl/cu128
```
> See [PyTorch official site](https://pytorch.org/get-started/locally/) for other versions installation.
Apple Silicon
```bash
pip install torch==2.8.0 torchaudio==2.8.0
```
**Step 2**: Install OmniVoice
```bash
pip install omnivoice
```
### Python API
You can use OmniVoice for zero-shot voice cloning as follows:
```python
from omnivoice import OmniVoice
import torch
import torchaudio
# Load the model
model = OmniVoice.from_pretrained(
"k2-fsa/OmniVoice",
device_map="cuda:0",
dtype=torch.float16
)
# Generate audio
audio = model.generate(
text="Hello, this is a test of zero-shot voice cloning.",
ref_audio="ref.wav",
ref_text="Transcription of the reference audio.",
) # audio is a list of `torch.Tensor` with shape (1, T) at 24 kHz.
torchaudio.save("out.wav", audio[0], 24000)
```
For more generation modes (e.g., voice design), functions (e.g., non-verbal symbols, pronunciation correction) and comprehensive usage instructions, see our [GitHub Repository](https://github.com/k2-fsa/OmniVoice).
